One-to-one and one-to-many have their own advantages and disadvantages. One-on-one learning is more detailed, and one-to-many can learn from each other, and the atmosphere is better. It depends on your own needs. I signed up for a one-to-many group class in the quiet guzheng, and not many people attended the class together. The key is that the atmosphere is good, so it depends on your own needs. I hope I can help you, and I hope to adopt it!
